[daip] Re: specifying a reference frequency in a FITS files for AIPS

[Eric Greisen]

I have looked at the rest of the data and have some doubts of its
correctness.  After scaling by frequency the baselines are of order
10^11 wavelengths which seems excessive.  The times are 40.8 + days
and are not in time order.  Note that the times are in days relative
to the date given but are kept in 32-bit float.  This loses accuracy
as soon as the day number exceeds 2 or so.  It is generally not a good
idea to write data with such large day numbers - chose a closer start
date.
